Web Hosting - Managing Disk Space
Few things are less exciting than managing the disk space that always seems to be in too short a supply. But few things are more important to the health and well being of your site.
The most obvious aspect of managing disk space is the need to have enough. If you have only a few dozen web pages, that's not an issue. But as the amount of information (web pages, database content and more) grows, the quantity of free space goes down.
That's important for two reasons.
All permanent information on a computer is stored on hard drives. Temporary information is often stored in memory only. The two components are completely separate, though they are sometimes confused with one another. As the amount of free space on the hard drive decreases several effects occur.
Here's one way to picture them...
Imagine you had a table with a certain area and you lay out playing cards on the table. At first, you lay them out in order, the 2 at the side of the 3, then 4, and so on. But then you pick up one or two cards from the middle and discard them. Then you add some more cards. Pretty soon things look pretty random.
Now cover the cards with a big opaque sheet of paper.
You want the cards to appear in order when displayed to someone. A special robot could be designed to always pick up the cards from underneath the sheet in order. Or, it could slide a hole in the sheet over the cards to display them in the correct order (2, 3, 4, ...), no matter what order they are really in. That's similar to how the operating system always shows you information in a sensible way, even though it's actually stored randomly.
Why should you care?
Real files are stored in pieces scattered around the drive wherever there is space for them. The more free space there is, the quicker the operating system can find a place to store a new piece. That means, if you delete the junk you no longer need (and free up more space) the system actually runs quicker. It helps create space you might need, and allows the operating system to store files for you faster.
But there's a second effect.
As you delete old files or change them, the pieces get more and more scattered. It takes the 'robot' longer and longer to fetch or display the 'cards' in order. Existing files are fetched and put together 'on the fly' (say, when you request a graphical page or a list of names). But, it takes longer to put together the web page when there are more scattered pieces.
So, the other aspect of managing disk space is to keep the pieces of the files more or less in order. A utility that does that is called a 'de-fragger' or de-fragmentation program. You can request that a system administrator run it, or if you have the authority, you can run it yourself. That keeps the 'cards' in order and allows for quicker access to them.
So, managing disk space involves chiefly three things: (1) keeping enough space to store what you need to store, and also (2) keeping enough free space to make new file storage quick and (3) making old file retrieval fast by keeping things orderly.
When only a few files are involved the benefit isn't worth the effort. But as the number and size of the files grow, to thousands of files or several gigabytes of data, the effect becomes more noticeable. Keeping things organized then makes a significant difference in performance.
Much of this can be automated using utilities. Some will delete files in a certain folder older than a certain date. A de-fragger can be set to run automatically during times of light usage, or quietly in the background at all times. Discuss the options with your system administrator and help him or her do the job better by keeping your house in order. You'll benefit by having a better performing web site.
Copyright law Understanding Copyright Law Copyright law is a set of laws that is used to regulate things such as movies, plays, poems, musical compositions, drawings, paintings, sculptures, software, photographs, sculptures, literary works, choreographic works, radio broadcasts, televisions broadcasts and more. Copyright law is only regulated to cover the manner or form in which the information or material is expressed. For instance, it does not cover the idea or facts which are represented in a work. In instances where a copyright does not exist, patents or trademarks may be in place which can impose legal restrictions. Copyright law states that the holder of the copyright has the right to make copies or reproduce the work to sell. They can also export or import the work, create derivative or adaptation of the original work, display or perform the work publicly and assign or sell the rights to someone else. Copyright law is set up to protect people from having someone do something with their copyrighted work or material. Someone that has a copyright may choose to exploit their copyrighted work, or they may choose not to. Many people debate whether copyright law and copyrights are moral rights or merely property rights. It is important to note that in the U.S. copyright law covers protection for published and unpublished works. Copyright law protection covers a work from the time it is created in a tangible form. The author or creator of the work immediately holds the copyright to the work and it is the property of the author or creator. No one else can claim copyright to it, unless the original copyright holder (the author or creator) gives or sells the rights to another person. Many people fail to understand that merely owning or possessing a work does not give them the copyright to it. Just because you have ownership of a copyrighted work does not mean that you own the copyright. Likewise, if you copy someone’s work and list their name on it, you are undertaking copyright infringement. Many people also fail to understand when copyright protection is secured. The moment a work is written or created and it is in physical tangible form or recorded it falls under copyright law. While it is recommended to register your work through the Copyright Office, if your work is not registered and someone steals your work, they have violated your copyright. Using a copyright notice is not required by law. However, many recommended that the copyright notice or symbol be used so remind the general public that the piece is under copyright. Anything that is created after 1977 is protected by copyright law for the lifetime of the author of the creator, plus an additional 70 years after the creator’s death. The public domain is a good source of information that is no longer under a copyright or work that was never under a copyright to begin with. Virtually all works that were created or published in the United States prior to 1923 are said to be in the public domain. Things that can be found in the public domain that are free of copyright law generally include generic facts and information, works that have a lapse in their copyrights (this encompasses works that were created prior to 1978) and materials and information put out by the United States government. In addition, you may find works in the public domain that are free of copyright law because it has been dedicated to the public domain. Important Networking Follow-Ups: How to Get Those Job Leads Calling When you leave a networking event, you may be buzzing at the prospects offered by all of those new contacts you made, but soon, the cold reality sets in. How will you be able to convert those contacts you made over a glass of wine into valuable business opportunities for you? Successful networking is all in the follow-up. If you’re looking for a job, following up is all the more crucial. Without touching base after a networking event, you become just another face in the crowd of job hunting hopefuls. The first important rule for following-up with networking contacts is to lay the foundations for the follow-up during the initial meeting. At networking events, there can be a lot of empty promises thrown around. Use that first meeting to convey the message that you haven’t gotten caught up in “networking fever” but instead that you are very serious about exploring the job opportunity that you’re discussing with your new contact. Ask the contact when would be a good time to follow-up with them, and then reiterate the information back to them at the end of your conversation: “I look forward to speaking with you Friday at 2 p.m.” If they don’t give you a specific time, then suggest one to them. This rule holds true even if your contact is giving you a lead on a job not with them but with another contact of their own. Let them know you appreciate the information by saying, “Thanks. I will plan on calling Mary on Monday afternoon at 1 p.m.” Not only will this convey your seriousness about the opportunity presented to you, but it may also get you some handy inside information, as the contact may reply, “Oh, no, Mary will be out of town until Thursday – call her then.” The next important rule to networking follow-ups is to follow up with EVERY lead a contact gives you. If a contact suggests that you call someone whom you know won’t really be able to help you in your job search, call him or her anyway. Otherwise, when your contact finds out you aren’t taking their advice, they may just decide not to give you any more the future and any business person can tell you that you never know from whom the most valuable lead will come some day. Keep the lines of communication open by giving any and all suggestions a whirl. Last but not least, do the actual following-up. Follow up with your contact exactly when you said you would, and in the exact manner you said you would (phone, email, letter, etc). If for some reason you can’t make contact at the arranged time, keep trying. If you haven’t made arrangements for a follow-up with a contact, then the rule of thumb is to follow-up with them as soon as possible after meeting them. Try to at least send an email or letter the next day saying what a pleasure it was to meet and that you look forward to talking more in the future, and then say in that note when you plan to follow-up with your contact by phone. Then, of course, stick to that new follow-up obligation. Even if the promises made by a contact while networking don’t pan out for you on the job front, don’t cross them off of your contact list. Keep them in the loop about your job search and your career goals. While they may not have been able to make if happen for you this time, you never know what they might be able to do for you in the future. Your most promising business contact may be someone you already know. |
